Use Hen in VS Code

The VS Code extension provides a rich authoring experience for .hen files.

What you get

• semantic highlighting for core Hen constructs
• hover help for directives and response-path accessors
• context-aware completions for imports, request references, schema targets, auth or session names, and response roots
• document links and go-to-definition for fragments and named references
• continuous import diagnostics, including missing targets and cycles
• Hen file icons for .hen files

Install locally

From the repository root:

cd editors/vscode-hen
npm run package

That produces a .vsix bundle in editors/vscode-hen/. Install it from VS Code with Extensions: Install from VSIX....

How it fits with the CLI

Use the extension for day-to-day authoring, then use:

• hen verify for authoritative validation
• hen inspect --output json when tooling needs machine-readable authoring data
